NEC LCD Technologies Ltd announced that it will begin shipping samples of its new 3.5-inch (8.9cm-diagonal) amorphous silicon TFT LCD this June. The new LCD is said to be suitable for installation in portable devices such as PDAs and portable GPS terminals.

According to NEC LCD, the product's luminance of 220cd/m2 and reflective ratio of 15 percent is achieved because of their super-reflective natural light TFT (SR-NLT) technology. The LCD is said to achieve a contrast ratio of 150:1, compared to a conventional product's 90:1. NEC LCD added that the product is approximately 10 percent lighter than conventional products, despite the integration of a timing controller and DC/DC converter.

"Through a combination of several of our core technologies, SR-NLT technology and adoptive design technology, NEC LCD Technologies has solved the long-time dilemma of how to achieve simultaneous high brightness and high reflective ratio of semi-transmissive LCDs," said Hidetoshi Usui, department manager in charge of product planning and marketing, NEC LCD Technologies, Ltd. "This breakthrough will offer a multitude of benefits to manufacturers of portable information devices, such as shortened lead time, as well as reduced cost and weight."

NEC LCD Technologies' new model will be shown at Display 2006, which is being held in Tokyo Big Sight, Japan, from April 19 - 21.
